Murder detective who investigated killing of Tupac has made a request in hunt to find Madeleine McCann

The former LAPD detective who worked on the Biggie Smalls (Christopher Wallace) and Tupac Shakur murder cases said he would be willing to take a look into the Madeleine McCann investigation.

Ex police officer Greg Kading has said in countless documentaries and interviews that he knows who killed the pair, given his involvement in both cases - Tupac was killed at 25 in 1996 and Biggie a year later, aged 24.

Since then, many have credited Kading and his task force for laying down the foundations for the 2023 arrest of Duane ‘Keefe D’ Davis for the murder of Tupac.

For what was once one of the most high-profile cold cases in the US, Kading now says he is open to taking a look at one of the most high-profile missing persons cases in Britain.

McCann, three, vanished from the Praia da Luz resort in Portugal back in May 2007.

She was on holiday with her parents Kate and Gerry McCann, and her younger twin siblings Sean and Amelie.

The parents were at a nearby restaurants when she went missing.

"Hey, I would love to come over there and live there for a year and work on that case," Kading told the MAD THAT PODCAST.

"I love going to England, I love the UK, I love Ireland, I love it up over there and if I had an opportunity to go over there and work, and live for a while, man, I would take it in a heartbeat.

"So get me on that case."

As for who killed Biggie Smalls, he added: "We know Tupac is no longer a cold case because that's been officially solved and somebody's being prosecuted for Tupac's murder.

"The Biggie case will always remain a cold case because it's an unprosecutable case. The shooter's dead, Suge (Knight) is already in jail and the third conspirator in that murder has immunity."

Kading previously explained the complex case to Vice: "Biggie was killed by an associate of Suge Knight.

"He hired a guy named Poochie to track down Biggie at the Petersen Auto Museum in March of 1997. And wait for him outside and he pulled alongside and shot either side of the car killing Biggie.

"Poochie was a blood gang member from Compton, well known to Suge Knight, well known to those in Suge Knight's circle.

"Poochie was a known gunman, a known violent gang member and is a perfect guy to recruit for that job.

"We don't know that Poochie acted alone, we know Poochie was involved but whether or not he had lay off guys or spotters, we don't know."

Poochie was murdered in 2002.

"So by the time we get the information about Poochie from the coconspirator, he's no longer chargeable," said the former cop.
